WINDOW.

SPECIFICATION forming part of Letters Patent No. 319,104-, dated June 2, 1885.

Application filed May 1, 1884.

To all whom it may concern:

Be it known that I, ANroN IlIATUSKA, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in \Vindows; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to a window which can be washed without inconvenience or the danger usually attending the washing of the common window, and which consists, principally of a blind-hinge constructed and placed vbetween the windowsash and the vertical standards to and between which said sash is pivoted; and it further consists of such a construction of the contiguous and rabbeted edges of said sash and standards that when the sash is oscillated to a horizontal position it will be therein maintained, substantially as hereinafter described, and as illustrated in the drawings, in which- Figure 1 is a front elevation of one of my improved windows. Fig. 2 is a horizontal transverse section of my invention. Fig. 3 is a horizontal transverse section of the sashframe and side standards, taken at the point of oscillation. Figs. 4 and 5 are perspective views of the sash-frame and the standards, showing their adjacent edges near their pivotal point. Fig. 6 is an edge view of the sashframe at its pivotal point. Fig. 7 is a perspective view of a portion of the standard and of the sash-frame at their point of pivotal connection.

Reference being had to the drawings, A represents a window-sash, placed between and pivoted to the vertically-sliding standards B B, preferably below their centers of length. These standards B move vertically up and down in the jamb of the sash-frame in the same manner identically as the ordinary windowsash, and are counterbalanced by the common ropes and pulleys and weights.

In order to prevent drafts of air passing between the contiguous edges of the sash and standards 13, I provide both the edges of the (No model.)

sash and of the standards with longitudinal rabbets a and 1), corresponding in depth and width and so arranged with reference to each other that when closed together the advanced surface ofthe edge of the side piece or standard, B, will fit into the rabbet a, and the advanced surface of the sash A will fit into the rabbet b. \Vhen in this position, the shoulders formed by these rabhets will face and bear tightly against each other, thus rendering it almost impossible for air to pass between the adjacent edges of the sash and standards, and especially will this be so if the shoulders made by the rabbets in the said edges be made at an inverse angle to the plane of the said rabbets.

In order to preserve and strengthen the shape of the edges of the standards B, (and, if desired, those of the sash also,) I coverv them with a sheet-metal plate, E, which conforms in every particular to the configuration of said edge its whole length, as shown in the drawings. This plate E covers nearly all of the outer and side surfaces of the standards excepting sufficient thereof to permit the fitting of the said parts in the j ambs of the saslrframe, and its side edges are turned inward to form tenons d, which enter corresponding longitudinal mortises, g, in the standards, thus avoiding the necessity of rivets to a very great extent.

' In order that the sash A may, when swung inward and downward to be washed, be supported wholly by and be maintained at right angles to the verticallyreciprocating stand ards B, I cut away the advanced surface of the edge of the standard immediately surrounding its pivotal point to the plane of the rabbet b, so that the shoulder, 0, made by said out will describe a segment of a circle struck from the said pivotal point. I also advance a corresponding area of the contiguous edge of sash A to plane of the advanced surface of said edge by means of a screw-plate, O, secured in position by suitable means, and having an extension, at, the upper surface of which is the obverse of the curvature of the shoulder c, which when the sash is closed it faces. Thus when the sash is opened it will,when about at right angles to the piece B, strike against the outer corner of the wall 0 and be maintained in such position, preventing the said sash from swinging down too far, and keeping the weight of the same always on the standards 13, substantially as shownin the drawings.

It is desirable in an invention of the kind herein set forth to have what is known as a blind-hinge. In order to accomplish this I place through suitable holes in the plate 0 and the plate E a pivotal rivet, 1/, the head of which is preferably next the inside surface of said plate 0. After passing through these plates the rivet 9 passes through the central aperture of the concavo-convcx disk-spring G, and has its contiguous end swaged until the pressure of the spring G holds the several parts through which the rivet passes closely together, and creates such a frictionbetween the contiguous meeting surfaces of the two plates that when the windowsash is swung inward it will not drop suddenly or violently. One of the plates-say C1nay, if desired, be dispensed with without injuring the etiicaoy of my window. In this event, however, a small portion of the said plate surrounding and con liguOuS to the blind-hinge is left remaining. In other words, a small iron plate is secured to the outer edge of the Window or inner edge of the standards near the pivotal point of said window,which affords a purchase for the rivet and disk-spring, and aii'ords a frictiongencrating surface.

The principal feature of novelty of the plates E is the tenons or flanged edges. These tenons dispense to a great extent with screws and rivets. I do not, therefore,wish to be confined to plates having the conformation of that shown, as it is obvious other conformations of the plates can be used without departing from the spirit of that part of my invention.

WVhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination,with the standards B B, having their inner edges covered by the plate E, and the window-sash A, having secured thereto the plate 0, of the rivet g. and the concave-convex disk-spring G, substantially as described.

2. The combination,with the standards B B,

having their inner vertical edges provided i The co1nbinati0n,with the standards BIB,

having their inner edges covered by the plate E, and the windowsash, of the rivet g and the concavo-convex disk-spring G, substantially as described.

In testimony that I claim the foregoing as my own I hereunto aflix my signature in presence of two witnesses.

ANTON MATUSKA.
